E-science grid facility for Europe and Latin America WAM Final Report Yassine LASSOUED & Ali Al Othman Coastal and Marine Resources Centre University College Cork Ireland

Itacuruçá, First EELA-2 Grid School, Application: WAM WAM = Global ocean Wave prediction Model Field: –Earth Sciences (Marine)‏ Objective: –forecast wave conditions around Ireland on a fine resolution, using high resolution winds obtained as boundary conditions from Met Eireann, for the periods and Resolution: –5 km (Met Eireann: 25 km)‏ Code: Fortran

Itacuruçá, First EELA-2 Grid School, Difficulties Input Data: –Bathymetry  160 KB –High Resolution Wind Fields  60 MB per file  1 file per month  100 years  Total size: 72 GB –Wave Boundary Conditions  50 MB per file  2 files per day  100 years  Total size: 3.6 TB

Itacuruçá, First EELA-2 Grid School, Difficulties Code compiled on 64b machine does not work

Itacuruçá, First EELA-2 Grid School, Done Transfer code and sample input data to a SE Script to: – download code and data from SE, – Rebuild directory structure as required, – Execute model on a working node, –Store outputs on SE. AMGA catalogue for processed data Script to check whether data have been processed Command line user interface: –Script to generate JDL files and submit jobs –Script to check jobs status –Script to download outputs

Itacuruçá, First EELA-2 Grid School, Synergy with Other Teams HMMER Team –Similarities in work flows and user interfaces –Build on user interface developed by Daniel and Michael Satellite Images Team –Potential for using same approach for seabed classification using large multi/single beam data

Itacuruçá, First EELA-2 Grid School, Next Steps Benchmarking [3-4 Months] Production [6-8 Months] –Transfer 3.6 TB of data to the grid –Deploy WAM on the EELA Grid Develop a user interface using GENIUS [9-12 Months]  Support needed
